Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471270, here are decompositions:
- 53 + 31471217 = 31471270
- 179 + 31471091 = 31471270
- 191 + 31471079 = 31471270
- 227 + 31471043 = 31471270
- 239 + 31471031 = 31471270
- 263 + 31471007 = 31471270
- 269 + 31471001 = 31471270
- 293 + 31470977 = 31471270
Showing the first eight; more decompositions exist.
